On the topic of running PiaF on a virtual machine, I have had great success with Virtualbox. It's free and it's fast. I don't get any choppy sound. I'm running a PiaF demo on my Macbook using Virtualbox and it's much better (and cheaper) than Fusion or VMware.
Hope this helps someone looking for a good virtualization solution for PiaF.
